Infiniti has provided a fleeting glimpse of the large sedan concept it plans to unveil at the 2018 Detroit motor show. We only have the one shot, but there are a few hints as to what we can expect. Alfonso Albaisa, senior vice president of global design, says the concept “heralds a new generation of Infiniti.”

Karim Habib, Infiniti executive design director, suggested the car will have a sloping, coupe-like roofline. We’d suggest the car will be a rival for the Lexus LS and Mercedes S-Class, albeit a slightly swoopier take on the theory.

Infiniti’s announcement comes just days after reports circulated that the luxury marque is planning a large sedan concept for Detroit – potentially a successor to the 2014 Q80 Inspiration, and the preview of an upcoming production model.

The car will be revealed on January 15 at the 2018 Detroit motor show.
